The US space agency conducted RS-25 single-engine Retrofit-2 test series at Stennis Space Center near Bay St Louis in Mississippi on Septemeber 30, the agency said in a statement. "This successful test series for the Space Launch System RS-25 engine puts us one step closer to manufacturing the first new set of engines for future Artemis missions to the Moon," said Johnny Heflin

The findings indicated that following the first recorded use of cannabis, patients were three times more likely to develop common mental health problems such as depression and anxiety.

These metal-rich NEAs were thought to be created when the cores of developing planets were catastrophically destroyed early in the solar system's history, but little more is known about them. A team of researchers from University of Arizona studied asteroids 1986 DA and 2016 ED85 and discovered that their spectral signatures are quite similar to asteroid 16 Psyche -- the largest metal-rich body in the solar system.

Unlike our solar system, which consists of a solitary star, it is believed that half of all star systems, like GW Ori where astronomers observed the novel phenomenon, consist of two or more stars that are gravitationally bound to each other. However, until now no planet orbiting three stars -- a circumptriple orbit -- has ever been discovered.

The gene, called retroCHMP3, encodes an altered protein that disrupts the ability of certain viruses to exit an infected cell and prevents it from going on to infect other cells.

According to researchers, including Paul Harrison from the University of Oxford, the most common symptoms were breathing problems, abdominal symptoms, fatigue, pain and anxiety/depression. "Research of different kinds is urgently needed to understand why not everyone recovers rapidly and fully from Covid-19. We need to identify the mechanisms underlying the diverse symptoms that can affect survivors," Harrison.

India has set a target of 450 GW of renewable energy by 2030. To achieve this, researchers are working towards renewable energy solutions, which should be sustainable with a limited carbon footprint.

The period, called Mars solar conjunction, happens every two years. This year it falls between October 2 and October 16. While the missions on the Red Planet will continue collecting data, engineers back on Earth will stop sending commands to them until October 16, the agency said in a statement on Tuesday. The Sun expels hot, ionised gas from its corona, which extends far into space.

Researchers at the University of Cincinnati used a carbon catalyst in a reactor to convert carbon dioxide into methane. Known as the "Sabatier reaction" from the late French chemist Paul Sabatier, it's a process the International Space Station uses to scrub the carbon dioxide from air the astronauts breathe and generate rocket fuel to keep the station in high orbit.

The object, GAL-CLUS-022058s, is located in the southern hemisphere constellation of Fornax (the Furnace). The image was nicknamed the "Molten Ring", which alludes to its appearance and host constellation.
